A study of thousands of middle-aged and older people has linked having more body fat and less muscle mass to changes in mental flexibility with age. The research also suggests that changes to
the immune system may play a role. Researchers from Iowa State University (ISU) in Ames analyzed data on...
Probiotics are trending in the world of nutrition these days and have received considerable attention from the medical research community. Evidence suggests that probiotics help mediate the host’s immune response, which is why some researchers believe that probiotics may help treat immune-related conditions such as allergies or eczema.

New research has revealed a mechanism through which fish oil, which contains omega-3 fatty acids, might reduce inflammation. A study that tested an enriched fish oil supplement found that
it increased blood levels of certain anti-inflammatory molecules. The anti-inflammatory molecules are called specialized pro-resolving mediators (SPMs), and they have a powerful...
New research using roundworms and mice has shown that one probiotic of human origin does not have to be alive to reduce markers of inflammation and promote health.
Probiotics are usually live, active bacteria that interact with the gut flora — the bacteria already present in the gut. Nutritionists and other...
Scientists at Northwestern University in Evanston, IL, measured brain activity relating to sound processing in athletes and nonathletes. They found that due to a stronger ability to lessen the background electrical noise in their brains, the athletes were better at processing signals from external sounds. The team reports the findings...
Family history, genes, and some lifestyle choices all influence a person’s risk of Alzheimer’s disease, but age is the greatest risk factor that researchers are aware of. Most people who receive a diagnosis of Alzheimer’s are at least 65 years old. In fact, after that age, the risk of developing...
Over years of practice, drummers appear to modify the way that the two sides of their brain communicate. According to a recent study, the cabling that runs between the two hemispheres of a drummer’s brain is significantly different from non-musicians. Playing drums is a unique skill. Drummers can complete different...
Researchers using a new method of assessing risk factors for prostate cancer have found an intriguing link between a lack of physical activity and an increased risk of this condition.
